Why the address bus is unidirectional and why the data bus is bi-directional in 8085?

In: Intel 8085 [Edit categories]

Answer:

The address bus is unidirectional becos address information is always given by microprocessor to i/o devices. The data bus is bidirectional bcos it takes the data from other devices & also give the data to other i/o devices

Why the address bus is unidirectional and why the data bus is bi directional in 8085?
The address bus is unidirectional in the 8085 because no bus slave device ever provides an address on the address bus - it always responds on the data bus. For the same reason, the data bus is...
Why the address bus is unidirectional in 8085?
The address bus is unidirectional because it is the CPU that tells the external hardware what address to use, not the other way around.
Why address bus and data bus are multiplexed in 8085?
To save pin count on the chip.
Why the data bus is bi directional but the address bus is one way only?
The data bus is used to read or write (hence bi-directional) to the data location selected by the address written on the address bus. You only need to write (one-way) to the address bus to select the...
Why data and address bus are multiplexed in 8085?
The data and address bus are multiplexed in the 8085 to reduce the pin count of the chip. 8 pins are saved, at the cost of one (ALE).
